Automatically estimating the complexity of texts for readers has a variety of applications, such as recommending texts with an appropriate complexity level to language learners or supporting the evaluation of text simplification approaches.

To this end, we create an English and a German three-way annotated evaluation dataset containing pairs of answers along with human judgment of their semantic similarity, which we release along with an implementation of the SAS metric and the experiments.

Based on this data, we formulate the novel task of recommending reader comments to journalists that are worth reading or replying to, i. e., ranking comments in such a way that the top comments are most likely to require the journalists' reaction.
